  Timer Synchronous Register (TSYR) 
TSYR is an 8-bit readable/writable register that selects independent operation or synchronous 
operation for the channel 0 to 4 TCNT counters. A channel performs synchronous operation when 
the corresponding bit in TSYR is set to 1.

Timer Synchronous operation 4 and 3 
These bits are used to select whether operation is 
independent of or synchronized with other channels. 
When synchronous operation is selected, the TCNT 
synchronous presetting of multiple channels, and 
synchronous clearing by counter clearing on another 
channel, are possible. 
To set synchronous operation, the SYNC bits for at 
least two channels must be set to 1. To set 
synchronous clearing, in addition to the SYNC bit , the 
TCNT clearing source must also be set by means of 
bits CCLR0 to CCLR2 in TCR. 
0: TCNT_4 and TCNT_3 operate independently (TCNT 
presetting/clearing is unrelated to other channels) 
1: TCNT_4 and TCNT_3 performs synchronous 
operation 
TCNT synchronous presetting/synchronous clearing 
is possible
